For what it's worth, I am 36 hours into owning my 2006 Exige and I feel like I've discovered driving TRUTH. I race Formula Mazda open wheel racecars (slicks, downforce, 1100lbs, 170hp) once a month and most guys complain about their 911s, M3s, Ferraris, feeling lame on the drive home from a race weekend. Once you drive a real race car even the most high performance beasts feel sloppy and heavy and blah.
Enter the Exige. This thing makes my Formula Mazda feel lame.
This is the stiffest car in existence. The feedback is visceral. Nothing else can touch it for driving "joy" and since the cost is not insane...you can rail it and wail it without stressing too much about the "what if" money factor.
And I'm only 600 miles into the break in and still babying it.
If you are buying your Elise/BMW as a performance car to rip in, maximize your driving skills, and to experience the raw joys of driving...you'd really miss out if you passed on the the Elise or Exige. If you are buying the car to take kids to the movies, etc...buy the BMW. Still a rad car...just not nearly the OH MY GOD experience of driving a Lotus. ZERO COMPARISON.
If if helps you any...I vascilated between a BMW, Porsche, and STi (test drove them all, hard) and I am so goddamn happy with my Exige that I cannot imagine not owning a Lotus for the rest of my life. It is incredible...brings tears to my eyes (literally).
Step up and experience the REAL ultimate driving vehicle. Buy the Lotus.
BTW -- I got my Lotus at Newport Lotus on Harbor Blvd in Newport Beach, CA and those guys rule. I flew in from the Bay Area (SF area) and they picked my girlfriend and I up at the airport in a Rolls Royce and treated us like rock stars. They I cannot thank them enough for making my first Lotus buy a terrific "old man memory" for my later years!!!!
